Pia's place was more than what I expected considering the room rate. It was very clean and spacious! Lovely old ladies at the lobby too! It is in a guesthouse so you get the usual services like daily cleanups, water and coffee/tea. Very quiet at night, you can only hear the birds. It is a bit far from BTS as it takes around 20min walk, but you can easily hail a tuktuk for 40baht or a motobike by Grab to and fro! There's a bank nearby the entrance for money exchange.
Big C is also a bike away, where you can get your quick fix of thai food from various restaurants and food court. Tons of cheap grocery items too!
If there's two of you, it is best to get a Grab taxi if you don't mind sitting in traffic to your destination. This is cheaper than using the BTS sometimes, and will require less walking ;)
Overall, I would stay here again. Highly recommended!
